WILLIAM L. ROORBAGH, OF PHILADELPHIA, PENNSYLVANIA.

RECEIVER, REGULATOR, AND COOLER FOR BEVERAGES UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 234,726, dated November 23, 1880.

Application filed July 13, 1880.

To all whom it may concern Be it known that I, WILLIAM L. RooRBAoH, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Receivers, Regulators, and

Coolers for Beverages under Pressure, which objects are accomplished and attained by my invention, which consists of a receiver having induction, eduction, and cooling pipes, a regulating valve or cook, and an agitator or stirrer, and asurrounding cooling tank or tub, all as will be hereinafter set forth.

Referring to the drawing, A represents a a tank or tub within which is supported a metallic receiver, B.

0 represents the inlet-pipe connected to the receiver and communicating with the fountain, keg, or barrel containing the beer, 850.

D represents a pressure-regulating cock at the top of the receiver, and E the eductionpipe communicating with the bottom of the receiver, intermediate whereof is a coil of pipe, F.

Within the receiver is a beater, agitator, or stirrer, G, consisting of blades attached to a vertical shaft, which is supported on a step, a, at the bottom of the receiver, and projects through the top thereof, where it is provided with a suitable crank or handle, I), for the purpose of rotating the stirrer.

The operation is as follows: The tub A is properly filled with ice and water, so that every part of the receiver below the line shown is subjected to the cooling action of ice-cold water. The pipe 0 is coupled to the fountain,

barrel, or keg, and the beverage therein is let on so as to enter the receiver B. The operator tries the faucet, (shown in dotted lines,) and should the beverage be wild, fly, or foam the cockor plug D is opened to permit the These (No model.)

escape of gas from the reservoir, and this is continued until the proper pressure is obtained, this being determined by the condition of the beer, which should be sufficiently lively without wildness and foam, the cock then being closed. The surface of the main portion of the receiver is in contact with ice or ice cold water, as has been stated, consequently the beverage next to that surface will be kept exceedingly cold, while that which is at the middle or at top is of a higher temperature and will be drawn off in such condition. The temperature should therefore be equalized. To accomplish this the stirrer G is occasionally operated, especially just before drawing a glassof the beverage, and thus the drink will be found cold and of uniform temperature, the proper degree of coldness of the water in the tub being maintained. The operation of the stirrer also prevents sediment or the settling of some solid matters which contribute to the flue flavor of the beverage, whereby said matters are passed off with the fluid.

As cleanliness is an essential element in beverages of the class to which my invention is applicable, the receiver is occasionally emptied and the pipe 0 disconnected from the fountain, barrel, or keg. Running water or steam is then introduced into the receiver through the pipe 0, and the stirrer G rotated so as to remove all substances adhering to the inner walls of the receiver and any deposits therein, and cause a thorough washing or cleansing of the receiver.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The receiver B, provided with an induction-pipe, O, eduction-pipe E, and coil F, in combination with the stirrer G, substantially as and for the purpose set forth.

2. The receiver with induction-pipe G, stirrer Gr, coil F, and eduction-pipe E, in combination with the cooling-tub A,'said receiver communicating with a fountain, 850., for beverages, substantially as and for the purpose set forth.
